Abstract:
Objective:To investigate the role of neutrophil CD 11b (nCD 11b), soluble CD 14 subtype (sCD 14-St) and mitochondrial coupling factor-6 (CF-6) in the risk stratification of disease outcome in neonatal sepsis and its clinical significance. Methods:The clinical data of 121 septic neonates from July 2019 to March 2020 in Shanxi Children′s Hospital were retrospectively analyzed. According to the neonatal critical illness score (NCIS), the neonates were divided into non-critical group (NCIS>90 scores) with 35 cases, critical group (NCIS 70 to 90 scores) with 49 cases, very critical group (NCIS<70 scores) with 37 cases. There were 25 cases with poor prognosis (death), and 96 cases with good prognosis (survival). The C-reactive protein (CRP), procalcitonin (PCT), nCD 11b, sCD 14-St and CF-6 before treatment were detected. The correlation between nCD 11b, sCD 14-St, CF-6 and disease severity was analyzed by Spearman method; the value of nCD 11b, sCD 14-St and CF-6 in predicting poor disease outcome in sepsis neonates was analyzed by the receiver operating characteristic (ROC) curve. Results:The nCD 11b, sCD 14-St, CF-6, PCT and CRP in critical group and very critical group were significantly higher than those in non-critical group: (414.68 ± 93.29) and (532.74 ± 101.85) MFI vs. (325.45 ± 71.90) MFI, (892.40 ± 113.72) and (1 249.53 ± 95.41) ng/L vs. (784.66 ± 103.72) ng/L, (84.79 ± 28.35) and (121.66 ± 34.27) ng/L vs. (42.59 ± 13.51) ng/L, (19.24 ± 6.30) and (34.96 ± 11.95) μg/L vs. (8.89 ± 2.24) μg/L, (109.49 ± 36.77) and (247.13 ± 82.06) mg/L vs. (56.84 ± 17.25) mg/L; the indexes in very critical group were significantly higher than those in critical group, and there were statistical differences ( P<0.05). Spearman correlation analysis result showed that nCD 11b, sCD 14-St and CF-6 were positively correlated with disease severity in sepsis neonates ( r = 0.719, 0.813 and 0.823; P<0.01). The nCD 11b, sCD 14-St, CF-6, PCT and CRP in poor prognosis neonates were significantly higher than those in good prognosis neonates: (618.58 ± 146.92) MFI vs. (374.55 ± 120.03) MFI, (1 516.91 ± 194.38) ng/L vs. (828.13 ± 175.67) ng/L, (165.84 ± 25.63) ng/L vs. (62.51 ± 16.75) ng/L, (43.46 ± 10.14) μg/L vs. (20.19 ± 6.30) μg/L and (321.09 ± 94.56) mg/L vs. (88.24 ± 29.19) mg/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of nCD 11b, sCD 14-St and CF-6 for predicting poor disease outcome in sepsis neonates were 0.763, 0.796 and 0.838 (95% CI 0.678 to 0.836, 0.713 to 0.864 and 0.760 to 0.899), and the AUC of combination the 2 indexes was 0.921 (95% CI 0.858 to 0.962). Conclusions:The nCD 11b, sCD 14-St and CF-6 are associated with the disease severity and prognosis in sepsis neonates, and can be used as markers for risk stratification of disease outcome and assessment prognosis.
